Harper Hospital treated 423 patients last week who were children, out of a total of 931 patients. The administrator calculates that they had 408 adult patients. Is the administrator's calculation reasonable? Estimate the number of adult patients by rounding the numbers to check the administrator's calculation.
Answers
Answer:
No, the administrator is wrong.
[tex]Adult = 500[/tex]
Step-by-step explanation:
Given
[tex]Total = 931[/tex]
[tex]Children = 423[/tex]
[tex]Adult = 408[/tex]
Solving (a): Is the administrator correct?
No, the administrator is wrong.
This is so because: when the number of children is subtracted from the total patient, the remaining number is not 408
Solving (b): Estimate the number of adults
By rounding up:
[tex]Adult = Total - Children[/tex]
Actual Figures
[tex]Adult = 931 - 423[/tex]
Round up
[tex]Adult = 900 - 400[/tex]
[tex]Adult = 500[/tex] -- approximately

Substitute the values of x and y into the expression -3x2 + 2y2 + 5xy - 2y + 5x2 - 3y2. Match that value to one of the numbers. What matches what I'm stuck 1. x = 0.5, y = -1/10 2. x = -1, y = -3 3. x =3/4 , y = 2/5 4. x = 0, y = 2.5 5. x = √2, y = √2 6. x = 2, y = -1 The answer thing. -1 9.17 14 -11.25 1.665 0.44
Answers
Answer:
1. Putting x = 0.5, y = -1/10 gives 0.44
2. Putting x = -1, y = -3 gives 14
3. Putting x =3/4 , y = 2/5 gives 1.665
4. Putting x = 0, y = 2.5 gives - 11.25
5. Putting x = √2, y = √2 gives 17
6. Putting x = 2, y = -1 gives - 1
Step-by-step explanation:
-3x2 + 2y2 + 5xy - 2y + 5x2 - 3y2
1. Putting x = 0.5, y = -1/10
-3(0.5)^2 + 2(-1/10)^2 + 5(-0.05) - 2(-1/10) + 5(0.5)^2 - 3(-1/10)^2
= -0.75 +0.02 - 0.25 +0.2 + 1.25- 0.03
= 0.44
2. Putting x = -1, y = -3
-3(-1)^2 + 2(-3)^2 + 5(3) - 2(-3) + 5(-1)^2 - 3(-3)^2
= -3 +18 +15+6+5-27
= 14
3. Putting x =3/4 , y = 2/5
-3(3/4)^2 + 2(2/5)^2 + 5(6/20) - 2(2/5) + 5(3/4)^2 - 3(2/5)^2
=- 27/16 +8/25 +30/20 -4/5 +45/16 - 12/25
= 18/16 - 24/25 + 30/20
= 18/16 - 96+150/100
= 18/16 +54/100
= 1800+ 864/1600
= 2664/1600
=1.665
4. Putting x = 0, y = 2.5
-3(0)^2 + 2(2.5)^2 + 5(0) - 2(2.5) + 5(0)^2 - 3(2.5)^2
= 12.5 - 5.0 - 18.75
= -11.25
5. Putting x = √2, y = √2
-3(√2)^2 + 2(√2)^2 + 5(√2.√2) - 2(√2) + 5(√2)^2 - 3(√2)^2
= -6 +4+10-4+19-6
= 17
6. Putting x = 2, y = -1
-3(2)^2 + 2(-1)^2 + 5(-2) - 2(-1) + 5(2)^2 - 3(-1)^2
= -12+2 -10 +2 +20 -3
= -1

Name:
1.) A deep-sea diver descends below the surface of the water at a rate of 5.5 feet each minute. What is the
depth of the diver after 1.3 minutes?
Write an expression to represent the problem:
Solve your expression in the box below and write your answer on the blank provided.
Answer
Answers
Answer:
The required expression for the depth is [tex]5.5t[/tex] feet.
The depth after 1.3 minutes is 71.5 feet.
Step-by-step explanation:
Let d be the depth of the sea below the surface of the water.
The rate of descending or the rate of increasing the depth, [tex]r= 5.5[/tex] feet/min.
Since, the rate is constant, so,
If the diver reaches the depth, [tex]d[/tex], in time, [tex]t[/tex]. So,
[tex]r= d/t[/tex]
[tex]\Rightarrow d=r\times t[/tex]
So, for [tex]r=5.5[/tex] feet/min, the required expression for the depth is [tex]5.5t[/tex] feet.
After time t= 1.3 minutes.
The depth, [tex]d = 5.5 \times 1.3 = 71.5[/tex] feet.

If a toy rocket is launched vertically upward from ground level with an initial velocity of 135 feet per second, then its height h after t seconds is given by the equation h(t) = -16t2 + 135t. How long will it take the rocket to return to the ground?
Answers
Answer:
The toy rocket will return to the ground at 8.44 seconds
Step-by-step explanation:
The height h of the toy rocket launched vertically as a function of the time t is given by:
[tex]h(t)=-16t^2+135t[/tex]
The rocket will return to the ground when h=0:
[tex]-16t^2+135t=0[/tex]
Factoring:
[tex]t(-16t+135)=0[/tex]
There are two solutions:
t=0, t = 135/16 = 8.4375
The first solution corresponds to the moment the toy rocket was launched, the second is the time taken by the rocket to return to the ground.
The toy rocket will return to the ground at 8.44 seconds
